Document Type and Number:
WIPO Patent Application WO/2023/197782
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Disclosed are a channel access method and apparatus, a device, and a storage medium. The method comprises: in a case that a channel state is idle and a channel back-off access process is determined to be restarted, executing the following steps: in a first channel back-off access process, obtaining a transmission opportunity, but abandoning transmission; and executing a second channel back-off access process, wherein the first channel back-off access process is the last channel back-off access process before the second channel back-off access process. The solution provides a mode of restarting a channel back-off access process on the basis that a channel is in an idle state.
